' PURIFYING APPARATUS FOR ACETYLENE GAS.

or- 1,661. Specification of Letters Patent.

Patented Oct. 3, 1911.

Application filed May 28. 1910. Serial No. 562.894.

To all whom it may concern:

Be it known that l, Hmxuicn [(xarr, a

subiect. of the German Emperor. residing at Weimar, Grand Duchy of Saxc-Woimarl Eisenach, Germany. have invented certain new and useful Improvements in lurit'ying Apparatus for .-\cetylcne tins, of which the following is a specification.

n% purifying apparatus for acetylene gas.

0 hat 'tple in which the centrally introduced gas pas es outwardly through a purifying layer or Wall.

The objects of the invention are to proridefor a more facile purifying operation, and for an easier cleaning and renewal of the purifying medium. .-\ccordingly the inven- T tion proposes, in contemplation of the first object, a container in which two chambers are separated by a frame which carries the porous purifying material and, in contemplation of the second object, a .longitmlimilly extensible and contractihlo frame, preferably a spiral spring upon which the puritying material is secured.

The invention is illustrated in the accompanying drawings, whercin- Figure l is a vertical central section; and Fig. 2 is a horizontal section.

Similar characters of reference designate corresponding parts throughout the views.

The apparatus embodies a vessel 1 permanently'closcd at it's llottom and closed at its upper end by a removablc lid 2. The i el'ior of the vessels} is divided into two separated CllilllllKBl'SI) and ,6, the gas being introduced into the chamber 5 and passing from thence to the chamber (3, which it leaves by way of the outlet pipe 9. The chamber-s5 and 6 are preferably concentrically related and are separated by a porous wall which consists of a frame 3, preferably a spiral spring as shown, and porous puri tying material 4, e. g., infusorial earth or asbestos, which in the present example is formed as a sheathing and surrounds the coils of the frame.

The gas intrmluction pipe 8 is located coaxially in the chamber 5 and, as compared with said chamber, is of relatively small diameter.

the gas passes into the chamber 5. In order that the separation of the latter and the chamber 6 may be complete the upper coil 11 of the frame 3 is constricted and is so arranged that its porous sheathing contacts This invention relates to improvements The pipe 8 is provided at suitable intervals with openings 7 through which 1 both with the pipe H and with the shcatlr ing of the adjacent coil 11. 1 The lid 2 lna'uictically closes the upperend of the vessel 1 and is secured in position by a cross brace 12. the ends of which are formed to engage in bay net slots provided at opposite points in the upper edge portion i of the cylinder 1. The brace l2 carries a Jscrew Sttlll it which projccts through the int and upon which a wing nut 1.3 is mountt ed, the object of the nut 15 and screw stcm it being to tighten said brace to the lid and thus insure the tirm retention of the latter and ot' the airtight closure of the container 1, it being oi course understood that suitable packing is employed in onnection with the lid.

The gas is introduced into the chamber 5 termediate space before reaching the purit'yiug wall. During this period a material pcrctmtage ot' the suspend 2d impurities fall to the bottom of the cham )er 5. ersingthe preliminary space incloscd by the purifying wall, the gas passes through the interstices of the wall and into the chamber i. If it be desired the outer chamber (3, hetwcen the sheathed coil spring and the vesscl 1, can be tilled or partially-tilled with a mixture of calcium carbid and ot pumice stone saturated with copper sultate for re moving the sullid of hydrogen and arseniurctcd lrvdrogcn. The chamber (3 can also be tilled with a mixture knowncommercially as puratilcn" which will retain both ammonia and phosphurctcd hydrogen.

it will be noted that. the outoryhamhcr (i is of such extent that the gi ls can collect therein and conscqiu-nt'ly pass through the porous wall at a low rate of speed. This is of advantage in that it allows of sullicient time for the accumulation of a deposit in the chamber 5 and for the mere deposit of impurities onthc surface of the porous sheathing. The expression more deposit is used with reference to a deposit. which is l essentially on the surface, as distinguished l'rom a deposit in the nature of an impregnation, that is, where the particles penetrate into the porous material, and which would result from a rapid passage of the gas through the porous wall. f Since the deposit of in'ipnrities is on the l surface only, it is possible to clean thewall in a simple and cllicient manner, In order I to clean the apparatus the lid 15 removed A fter travand the spiral frame is Withdrawn from the container. Thereupon the frame is manipulated, that is, it is alternately extended and contracted in the manner of playing an accordion, an act which produces deformations of the surface of the porous layers and consequently causes the impurities deposited on the layers to be mechanically thrown into space' It is of course a parent that the degree of separation of tiie spiral coils and the consequent compactness of the intermediate layers of sheathing may be regulated by any suitable means, e. 9., a weight.

Having fully described my invention, I claim:

1. A gas purifier consisting of a container, a porous purifying wall dividing the container into separate chambers, the purifying wall embodying a longitudinally extensible and contractible frame and porous purifying material secured by the frame, and a gas inlet pipe disposed in one of the chambers and at a distance from the wall, the other chamber having a gas outlet pipe;

2. A gas purifier consisting of a container,

and a gas inlet pipe disposed coaxially in the inner chamber at a distance from the Wall, the other chamber having a gas outlet pipe.

A gas purifier consisting of a containerhaving gas inlet and outlet means and a purifying Wall disposed within the container and embodying a longitudinally extensible and contractible frame and porous purifying material secured by the frame.

4. A gas purifier consisting of a container having gas inlet and outlet means and a purifying wall disposed Within the container and embodying a spiral spring frame and a porous sheathing fitted in the frame.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
